  Hash : 378653f8
  Message : D3D: throw a perf warning for uniform block We had translated an uniform block only containing a large array member into StructuredBuffer instead of cbuffer on D3D backend for slow fxc compile performance issue with dynamic uniform indexing. This patch throw a warning if a uniform block containing a large array member fails to hit the optimization.
